【Abstract】 If the amplitude of the trainer is too large,it will cause direct injury to the human body during training and reduce the service life of the instrument itself. In order to control the amplitude of vibration within a reasonable range,a knowledge expression and mapping method of the core strength trainer vibration suppression parameter set is proposed. Based on D’Alembert’s principle,the mass center linear velocity matrix is calculated by calculating the eccentricity of the clearance of the connecting shaft of the trainer. The sinusoidal trapezoid function is used to plan the vibration suppression curve according to the dynamic model,and the angular velocity in the curve is parameterized,and the mapping parameters are calculated by using the discrete angular position difference. The experimental results show that the proposed method can reduce the vibration of the core strength trainer in a very short time,and meet the basic requirements of the core trainer,and the expression and mapping results are true and effective,which has a certain practical application value.更多还原
